posted on 2021-01-05, 19:05 authored by Li Wang, Wenping Liu, Jie Ding, Hualian Zhang, Yudie Zhu, Feng LuoSeparation of Xe/Kr mixtures is significant
considering their applications
and environmental hazards. However, the similar chemical and physical
properties of Xe and Kr raised the difficulty of separation. In this
work, a new metal–organic framework (denoted as ECUT-50) was synthesized and investigated. ECUT-50 exhibited
obvious adsorptive selectivity of Xe over Kr in both 298 and 273 K.
The effective Xe/Kr separation ability was proved using a breakthrough
experiment. The excellent separation ability could be due to the suitable
pore size of ECUT-50 which matches well with a single
Xe atom.
